The main formula is A= 2pi r (H + r)
H= 9, and r= 11
so A= 2 *3.14*11* (9 + 11) = 1381.6 cm²
so the answer is <span>1380 cm2</span>
<span>Sqrt(5x) * Sqrt(x) + 3
= 5^(1/2) * x^(1/2) * x^(1/2) + 3
= 5^(1/2) *x +3
=5^(1/2)*x^(2/2) +3
=Sqrt(5*x^2) +2
So the answer is A </span>
180
<span>3*60 </span>
<span>3*3*20 </span>
<span>3*3*4*5 </span>
<span>3*3*2*5 </span>
<span>which simplifies to 2^2*3^2*5
</span>
I hope I helped!
Answer:
210 student's
Step-by-step explanation:
80 students chose the aquarium.
60 students chose the science center.
30 students chose the planetarium.
40 students chose the farm.
The students can't vote for more than one place, so you just add all the numbers together.
80 + 60 + 30 + 40 = 210 students
